plump

The word 'plump' emerged in Middle English, likely as an onomatopoeic or expressive formation meant to imitate the dull, heavy sound of something soft falling or to suggest a blunt, rounded shape. It is related to similar words in Middle Dutch ('plomp', meaning blunt) and Middle Low German ('plump', meaning clumsy or blunt). This core sense of bluntness or heaviness evolved to describe both a full, rounded physical appearance and a sudden, heavy manner of movement or action. The verb sense meaning "to choose decisively" developed later, likely from the notion of a direct, unhesitating action, akin to falling heavily on one side of an argument.

The word 'plump' is a Middle English word of imitative or expressive origin, likely meant to evoke the sound of something soft and heavy falling or the visual impression of a rounded, full shape. Its functional role is as a root adjective and verb.
